Where do I turn as my emotions change?

In reading Made to Crave, Lysa makes a statement about cravings and linking to our emotions. 

"Food was my comfort.  Food was my reward. Food was my joy. Food was what I turned to in times of stress, sadness, and even in times of happiness."

Food is meant to be a part of us and part of fellowship, but it cannot be the key point or the focus of my thoughts.
